DETAILED DESCRIPTION

[0022] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0023] Embodiment:

[0024] As Figures 1-3As shown, a particle filtering device for a film blowing machine includes a main box 10, a secondary box 20, a first filter plate 30, a second filter plate 40 and a lifting mechanism. The main box 10 is provided with a feeding port 11 at the top and a first discharging port 12 at the bottom. The first filter plate 30 includes a mesh plate 31, a hinged block 32 and a lifting block 33. The mesh plate 31 is provided with clamping blocks 34 at the bottom of both sides. The hinged block 32 is hinged to the inside of the main box 10. The lifting mechanism includes an electric telescopic rod 51 and a connecting rod 52. The electric telescopic rod 51 is arranged at the top of the main box 10 and extends into the main box 10. The end of the electric telescopic rod 51 is connected perpendicularly to the middle of the connecting rod 52. The lifting block 33 is provided with connecting blocks 36 at the top of both sides. The middle of the connecting block 36 is provided with a waist-shaped hole 37 matching the diameter of the connecting rod 52. The two ends of the connecting rod 52 are inserted into the waist-shaped hole 37 to movably connect the connecting blocks 36. The connecting position of the connecting rod 52 is higher than the mesh plate 31, so that the mesh plate 31 and the plastic particles do not interfere with each other. The secondary box 20 is arranged on the side of the main box 10 away from the hinged position. The main box 10 is provided with a material passing port communicating with the secondary box 20. The secondary box 20 is provided with a second discharging port 21 on the side away from the material passing port. The second filter plate 40 is arranged in the secondary box 20 in a downward inclined manner along the direction from the main box 10 to the secondary box 20. The higher side of the second filter plate 40 is located at the bottom of the first filter plate 30. The higher side of the second filter plate 40 is provided with a supporting block 13. The two sides of the second filter plate 40 are detachably connected to the bottom side of the supporting block 13 and the second discharging port 21, respectively. The detachable connection can be achieved by the same way as the first filter plate 30, i.e., clamping the supporting block 13 and the second discharging port 21, respectively.

[0025] The working principle of the above technical solution is as follows:

[0026] The plastic particles can first enter from the feeding port 11 and be filtered by the mesh plate 31 of the first filter plate 30. When the first filter plate 30 accumulates, the electric telescopic rod 51 is started to extend, thereby lowering one side of the first filter plate 30. The hinged block 32 of the first filter plate 30 rotates along the hinge and tilts towards the secondary box 20, so that the plastic particles passing through the first filter plate 30 roll. During the rolling process, larger plastic particles can be removed from the first filter plate 30, and part of the appropriate plastic particles can pass through the first filter plate 30. The plastic particles that do not pass through the first filter plate 30 can fall onto the second filter plate 40 of the secondary box 20 through the material passing port, continue to roll and be filtered again. The plastic particles passing through the second filter plate 40 can fall to the bottom of the secondary box 20 and gradually return to the main box 10, and finally be discharged from the first discharging port 12 to the film blowing machine. The plastic particles that do not pass through the second filter plate 40 can be rolled and discharged from the second discharging port 21 for subsequent processing.

[0027] In another embodiment, as Figure 1As shown, the device further comprises a scraping mechanism, which comprises an electric telescopic rod two 61, a mounting block 62 and a scraping sheet 63, the electric telescopic rod two 61 is arranged outside one side of the main box body 10 at the hinge, the side of the main box body 10 is provided with a support plate 14 supporting the electric telescopic rod, the end of the electric telescopic rod two 61 extends to the bottom of the first filter plate 30, the mounting block 62 is arranged at the end of the electric telescopic rod two 61, the scraping sheet 63 is selected from a rubber sheet and arranged on the mounting block 62, and the top side of the scraping sheet 63 abuts against the bottom side of the first filter plate 30.

[0028] After the first filter plate 30 is inclined, the scraping sheet 63 abuts against the bottom side of the first filter plate 30, the electric telescopic rod two 61 can be started to drive the scraping sheet 63 on the mounting block 62 to stretch and retract, the scraping sheet 63 can extrude the bottom side of the mesh plate 31, and the plastic particles stuck in the filter holes of the first filter plate 30 are pushed out, so that the blockage is avoided.

[0029] In another embodiment, as shown in the figure, Figure 1 The second discharge port 21 is provided with a movable door plate 22.

[0030] The movable door plate 22 can be closed during the rolling of the plastic particles on the second filter plate 40, so that part of the suitable plastic particles do not roll out too fast and directly leak out, and after the rolling of the plastic particles is stopped after the second filter plate 40 is filtered, the movable door plate 22 can be opened again to concentrate the discharge.

[0031] In another embodiment, as shown in the figure, Figure 1 The bottom of the auxiliary box body 20 is inclined downward in the direction towards the main box body 10.

[0032] The plastic particles falling to the bottom of the auxiliary box body 20 fall back to the main box body 10.

[0033] The above-described embodiments only express the specific implementation of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent range of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection range of the present application.
